COMBINED `WA'l'lF-CLOSET `AND FLLUISHING-RESERVOIR.

SPECIFICATION refining peut of Lettere patent No. 716,315,1etea Deeember 1e, 1902.

. of Braintree, in the countyofNorfolk and State of Massachusetts, have invented a new and useful Combined Water-Closet and Flushing-Reservoir, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to a combined watercloset and flushing-reservoir; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the descriptionof 1 the accompanying drawings and to the claim hereto appended and in which my invention is clearly pointed out.

Figure 1 of the drawings is a plan of a water- `closet embodying my invention with a por-A Fig. 2 is a sectional eletioncut in section. vation of the same, the cutting plane being on line A A on Fig. 1. Fig. 3 is a rear elevation of the.l same with the rear covering# plate`removed. Fig. et is an elevation of the side opposite to that shown in Fig. 2 with the equalizing-valve shown in section.

In the drawings, 1 represents the closetbowl proper, which may be of any usual or well-known form and has formed in one piece therewith the annular reservoir 2, which surrounds the upper portion thereof,asshown. An annular Iiushing-passage 3 is located in the lower inside corner of said reservoir and is provided with the usual discharge-orices 4 and has communication with said reservoir 2 through the port:5, said bowl, reservoir, and Bushing-passage being combined in a single piece of earthenware, as shown. The inner Wall of the reservoir 2 or the outer wall of the iiushing-passage has secured thereto at the rear the plate 6, which is provided with a port 7, corresponding in size and shape to the port 5, through the outer wall of the ilushingpassage, said plate 6 being also provided with upper and lower grooves to receive the upper and lowered ges of the slide-valve 8, which is also preferably provided with a port 9, corresponding in size and shape to the ports 5 and 7, and when saidvalveis moved into position to `uncoverthe ports 5 and 7 the water contained inthe reservoir 2 will pass into the flushing passage 3 and be discharged therefrom through the orifices 4 into the bowl I Application filed July Z2, 1602. Serial No?. 116,534. (No model.)

to flush it, the water in said reservoir when full having a pressure of twentypounds to the square inch, more or less. The reservoir is charged with water from the service-pipes of the city or town water-supply through an equalizing-valve 10, constructed to meet the requirements of each individual case.

The valve 8 has connected thereto the valvestein 11, which has a bearing in the metal bushing 12, set in the outer wall of the reservoir 2 and clamped thereto by the nut 13, and has screwed upon its outer end the cuplike gland 14 to form a stuffing-box around said stem, as shown in Fig. 1. The outer end of the stem 11 has connected thereto one end of a lever 15, which is fulerumed upon a stud 16, set in an ear 17, formed integral with and projecting outward from the. outer wall of the reservoir and provided at its front end with a suitable hand-pad 18, and has interposed between its forward arm-and a socket 19, formed in the outer surface of the earthenware closet, as shown in Fig. 1, a spring 20, the reaction of which will closethe valve 8 when the hand is removed from the pad `18.

The equaliZing-valve 110 is mounted in a casing 21, one end of which is firmly secured in any suitable manner` to the earthenware closet and has secured in its other end the supply-pipe 22, the stem of said valve projecting downward through a stuffing-,box 23,

and the yoke 24eand is surrounded between said yoke and a collar 25, formed upon or secured to the end of said stem, by a spring 26, said spring being made of a stiffness suicient to counteract that portion of the pressure of the city or town water-service which exceeds the pressure maintained in the reservoir when filled.

An air-valve 27 is constructed and arranged to admit air to the reservoir 2 when the water is discharged therefrom and allow it to escape therefrom until the water has risen to a desired given level, when said air-valve will be closed, and as the water continues to rise in the reservoir the air still remaining therein will be compressed untilthe desired pressure per square inch is obtained in said reservoir, when said pressure in thereservoir, combined with the tension of the spring 26,

will close the valve 10, in which condition the parts will remain until the slide-valve Sis IOO moved outward by pressing the front end of the lever l5 inward, when the water contained in the reservoir will be discharged into the Aiiushing channel 3 and thence through the orifices 4 into the bowl to flush the same, and as the pressure in the reservoir is reduced by the discharge therefrom of its contents the excess of pressure in the supply-pipe over that exerted by the tension of the spring 26 will cause the Valve l0 to be automatically opened and the reservoir to be again filled as soon as the hand is removed from the pad 18 of the lever l5.

The operation of my invention will be readily understood from the foregoing without further description here.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

In a water-closet the combination of thev closet-bowl, a flushing-rim arranged above and overhanging the upper portion of the inner surface of the wall of the bowl, and hav- .ing formed therein an annular flushing-passage provided with' a series of discharge-orices opening therefrom into said bowl; an annular oval reservoir surrounding and eX- tending over said flushing-passage and so arranged relative'thereto that the bottom of said iushingpassage shall be at as low a level as the bottom of said reservoir; means for admitting/water to said reservoir; and a suitable valve for opening and closing cornmunication between said reservoir and flushing-passage.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 21st day of July, A. D. 1902.
